To provide a performance evaluation device that can evaluate impacts of arbitrary factors on a performance of a plant.SOLUTION: A performance evaluation device comprises a performance evaluation unit that, on the basis of a function indicative of a relationship between a performance of a plant and one or a plurality of parameters, moves a point indicative of a performance when each of the parameters takes a prescribed value so that at least one of the parameters is a prescribed reference value along a multi-dimensional curved surface the function indicates, and thereby, calculates the performance when the parameter is the reference value.SELECTED DRAWING: Figure 2 【課題】プラントの性能に対する任意の要因の影響を評価することができる性能評価装置を提供する。【解決手段】性能評価装置は、プラントの性能と一つまたは複数のパラメータとの関係を示す関数に基づいて、前記パラメータの各々が所定の値をとるときの前記性能を示す点を、前記関数が示す多次元曲面に沿って、前記パラメータの少なくとも一つが所定の基準値となるように移動させることによって、当該パラメータが前記基準値となったときの前記性能を算出する性能評価部、を備える。【選択図】図２
